' Be it knownthat I, RICHARD Bon'N'rnnn,

fa citizen of the United States, and a resident of the city and county of San Francisco and State of California, haveinvented a new anduseful Improvement in Wave-Motors, of which the following is a specifica- '-tion.-' My; invention relates to wave unotors,

wherein a float, operated by the movement of the waves, imparts an intermittent move ment to a conveyer, which in turn raises weights to an incline abovea wheel having pockcts-on the periphery thereof, the said Weights in turn rotating a wheel; and the objects of my invention are, first, to provide improved means for transforming the reclprocating movement ofuthe waves into a.

continuous rotary movement, by means of which power may be generated; second, to provlde means whereby weights are received from a lowerincline below a power wheel 4 and carried to an incline above the power wheel; third, to provide means which wil operate independently of the float for the purpose of assisting in the raising of the weights to an upper incline fourth, to pro- '-Vide improved means for transferring. a reciprocating movement of a float to a conveyer; fifth, to provide improved means for retaining weights on a conveyer; and sixth, to provide improved means for automatically releasing the weights from the conveyer and conveying them onto an npper incline.

I accomplish these several features by means of the device disclosed in the draw ings forming apart of the present specification, wherein like characters of reference are used to designate similar parts througln out the said specification and drawings, and m which-- Figure 1 is a broken side elevation of the conveyer, disclosing the manner in which the conveyor is operated by a cable and also the manner in which the weights are com veyed from the lower incline to the upper incline and delivered onto the wheel.

Fig. 2 is a broken side elevation of the float, disclosin the manner in which the said float-is sli ably and pivotally mounted to the stationary piles and the manner n which the cable is operated, hi h n $31111 tinuation of the Specification of Letters Patent.

Fig. 7 is an enlarged sectional view taken on line,YY of Fig. 6 of the drawings in the direction indicated by the arrow.

Fig. 8 is a broken detailed view of the operating levers in one extreme position and Fig. 9 is a similar viewof the operating levers, excepting that the said levers are shown in the opposite extreme position.

Fig. 10 is a broken detailed viewon an enlarged scale of the bell-crank levers secured to the chains of the endless conveyor, by means of which the weights are retained on the conveyer whilev said weights are bcslidably mounted by means of rollers 2 5 thereon within parallel vertical channels 4 secured to stationary piles. Pivotally secured on the-axis of the rollers 2 and on each side of the float are upwardly extending standards 5, also slidably mounted withtending standards,5 are rotatably mountedgrooved pulleys 9, over which pass parallel cables having one end thereof-secured to ofthe cables 1 on the endsof a shaft 18', pivotally mounted the float 1, as'at 12. The other ends of the cables 10. pass over rollers 14 rotatably mounted upon a suitable frame-work 15 at a suitable distance from the float 1. After passing over the pulleys 1 4, the inner ends 10 are-secured to levers 16 upon the frame-work 15. v

Counter-weights 20 are secured just below the ends of thecables 10 to the levers 16. To the shaft 18 are rigidly secured beams 22 and to the ends of the beams 22 are secured operating bars 25 and 26, the said operating bars 25 and 26 being bifurcated at, the upper ends, one of the said bifurcations on each set of bars being con siderablyextended, as at 27 and--28, re-

spectively.

vAlso mounted within the frame-work 15 are the upper and lower shafts '30 and 31,

said shafts having secured thereto suitable sprockets 32 and Engaging both the sprockets 32 and'33 is a suitable endless conveyor 34, having pivotally mounted thereon bell-crank levers 35, the lower ends of-which are inwardly turned, as at 36. The extensions 37 ofthe bell-crank levers 35 are arranged to; support the reduced ends 38 of weights 39 having grooves 40 thereon arranged-to engage the tracks 42 of the upper incline and similar tracks 14: of the lower incline.

The endless conveyer '34 is provided with suitablerollers 46 at regular intervals, said rollers being arranged to. be engaged by a suitable channel' 4l8 for the purpose "of retaining those links of the endless con'veyer 34k to which are pivoted the bell-crank levers 35 in a suitable supporting position on that side of the endless conveyer 34;, which raises the-weights 39;

The upper incline carriesthe weights 39 to a stop 50, whichis pivotally secured, as

at 5 2, to a bracket 53. A lever 56 is'formed,

integral with the stop 50 and is arranged in the-path of pockets 58securedto a'wheel 59, which is in turn rigidly secured to a shaft 60, rotatably mounted '7 within the frame115.

To the shaft 60 shaft 65 by means of a suita 1e belt 66, said shaft 65be'ing rotatably mounted in suitable to slack andlower the counter-weights 20.

, is also rigidly secured a pulley 62, which drives a ulley 64 on a veyer 3-1, while the float 1 is greater in which are being supported on the bell-crank levers 35 of the conveyer 34.

The operation is asfollows', A wave moving toward the float engages the inclined portion 3 thereof and raises the said float, thereby allowing the cables lO Inasmuch as the counter-weights 20 are. greater in weight than all of the weights 39, being raised on one side of the conveyer, the said counter weights 20,, by means of the lever 16 and shaft 18, "will operate the beams 22 and cause the parallel operating "bars 26 to move upward and the bifurcated ends toengage the connecting rods 29 between the parallel chains of-the endless con veyer'3i and move-that side of .theendless conveyer'34, containing the'weights' 39, up-

ward, I v

At the same time, the parallel operating bars'25 on the opposite ends of the beams .22 will move downward until the parallel operating bars 25 and 26 assume the position disclosed in-Fig. 9 of the drawings. As the wave passes the'fioat 1, and the outer end thereof returns tothe hollow between the waves, the said float will pull on the cables 10 and raise the counter-weights 20,. thereby reversing the movement of the beams 22' so that the parallel operating bars 25 will move upward and the bifurcated ends thereof will engage the connecting rods 29, resting upon the bifurcated portion of the parallel operating rods 26 and again move that side of the endless conveyer 34, on which the weights 39 are mounted, upward until the parallel. operating rods25 and 26 assume the position. disclosedin Fig. 8'of the drawings.

'The extended portions 27 and 28 of the rods 25 and 26, respectii ely are extended so as to facilitate the engagement of the upper ends of the rods 25 and 26 with the con necting rods 29.

As the crest of the wave passes the front end of-the float 1 and reaches thepoint illustrated in Fig. 2-01? the drawings, itis evident that as the rear end of the float Iis raised it will in. turn raise the upwardly eX- tending standards 5, pivotally secured thereto, and, by means of the grooved rollers 9 on the upper ends of the'said standards 5, will raise-the cables 10 and thereby exert a further pull upon the said cables 10.-

Inasmuch as the float l is greater in weight than the counter-weights 20 and weights 39, it is obvious that as it falls between the Waves it will readily lift the co1u1ter-weights20 and the" weights 39 on the endless conveyer 34. The weights39 are retained upon the endby means of the inwardly turned portions 36 on the lower ends of, the bell-crank levers 35, said portions 36 being arranged to engage and slide on the channels 48 in which that side of the endless conveyer 34 rides soas to retain the extensions 37 of the bellcrank levers 35 in such an inclined position; that the weights 39 thereon will tend to roll, by gravity, toward the endless con-. veyer 34 and away from the free ends of the said extensions 37, until a weight 39 "is slightly above the tracks 42 of the upper incline, when the extensions 36 of the bell-, crank levers 35 will clear the upper ends of the channels 48 and the weight ofthe weights 39 will cause the levers '37 to drop a-short distance and deliver the weights 39 onto the tracks 42 of the upper incline (see Fig. 11), the said tracks 42 engaging the grooves 40 of the said weights 39.

The weights 39 roll down the tracks 42 of the upperincline until they are engaged by the stop 50. As eachpocket 58 of the wheel 59 engages the arm 56 ofthe stop 50, it will raise the said arm 56 and release one of the Weights 39. Simultaneously, the extension 51 of the stop 50 will be lowered and engage the reduced portion 38 of the second weight 39 and prevent the same from rolling down the tracks 42 of the upper incline until the wheel 59 has rotated a sufficient distance to remove the pocket 58 from under the extension 56 of the stop 50,when a suitable spring, shown in Fig. 1 of the drawings, will return the stop 50 to a position where it will be in the path of the reduced portion 38 of the next weight 39 and at the same time will raise the extension 51 of the stop 50 and remove the same from in front of the said reduced portion 38 of the said next weight 39, thereby allowing the said weight 39 to roll down the tracks 42 of the upper incline, until the said reduced ortion 38 is arrested by the stop 50. v The weights 39 thus loaded onto the wheel 59 will cause the said wheel 59 to move in the direction indicated by the curved -arrow in Fig. 1 of the drawings, thereby rotating the shaft 60 and the pulley 62 thereon and imparting a continuous rotary. movement, by means of the belt 66, to the pulley 64 mounted upon the shaft 65.

As the weights 39 in the pockets 58 reach the lowermost portion of the periphery of the wheel 59, the said weights 39 are delivered onto a lower incline 44, which incline 44will deliver the weights to the lower por tion of the endless conveyer 34, where they are again engaged by the extensions 37 of the bell-crank levers 35 and raised interitently bythe movement of the float 1 to the upper incline 42.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent is frame-workpawheel having pockets on the periphery thereof and rotatably mounted within the frame-work a series of weights adapted to engage the pockets; an upper incline arranged to deliver weights to'the.
